How to create a matrix with variables

[humbertomoraes]

I have 12 double variables (not an array) and I wanted to put them all in a 4 by 3 matrix. I was trying to use the Build Matrix function but I could not figure out how I would define which variable would be in each position of the matrix.

Hi humberto,

there are functions like BuildMatrix and SetMatrixElement - you should be able to build your matrix using them.

Then there are also BuildArray and ReplaceArraySubset. Using them you can create a 2D array, which you could convert to a matrix later on.

Why do you need a "matrix"? Would a 2D array be sufficient too?

Hello GerdW,

I started thinking about using a matrix because I could not find how to create a 2D array using the Build Array function. I found out a couple minutes ago that I could use the Initialize Array function to create a 2D array. Is there any way I can do the same using just the BuildArray function?

Thank you for helping!

Hi humberto,

I thought this would be explained in the beginner tutorials for LabVIEW, offered for free on NI's website:

Pretty easy, eh!?

Please go through those tutorials. Study the example VIs coming with LabVIEW.

It will help you to learn LabVIEW!

Yeah, looks so. Sorry for that, I'm starting in Labview and I haven't seen that tutorial (just the self-paced video training) because I'm using Labview in a college and never bought it myself to access other courses. But I'll check that better.

Thank you very much GerdW.
